I would dump the kit lenses first off. Even if you don't get much money back, they are just taking up space...

If you are planning on staying with crop sensors, then the 17-55 2.8 IS ef-s would be my first choice. It isn't a really exciting range, like the fisheye or 10-22, but it is solid. And you need a solid lens to build on.

Next up would be 24-70 2.8, 16-35 II 2.8 (though might be too much, so 17-40 is just as good IQ, but f4). Maybe 24-105 f4IS?

Fisheyes are rad, but the effect will get old kinda quick, I usually just use it every once in a while. It is sweet on the 5d/5dII though and the colors are really nice.

If you use telephoto more then wide, the 85 1.8 is a really nice lens as well, great for the price. And the 135 f2 L is becoming my favorite piece of glass. Ever. Or, the 70-200 f4 IS should be in your price range, and that is a hella sharp lens.

I'd go with the 10-22. I'm shooting with a crop sensor Canon, and my Sigma 10-22 is my favorite lens for climbing shots. Without a ultra-wide angle lens, it's sometimes impossible to get far enough away from the subject to get what you want in the frame. Especially in tight boulderfields like HP40. You can also acheive some interesting foreshortening effects with an ultra-wide.

Definitely ditch the shorter of the two kit lenses, as it will quickly become redundant. You may still get some mileage out of the longer kit lens, even though it's probably pretty slow, especially zoomed all the way in to 300mm. But if you're shooting outdoors in good light, it will probably work well enough until you get the itch (and the money) for a f2.8 70-200, or something of the sort.

Hey guys.... I think I am gonna take Wes's suggestion and go for the 17-55 f2.8.

Altho its $2000, so another $700 more than I was going to spend but like he said, its something to build on.

I like my 70-300, although its not flash and crap in low light, its taken some alright photo's outside at distance.

I don't know much about Canon kit lenses and I've never owned a kit lens myself. But to me they do have a purpose if you aready have one. They are decent quality (esp stopped down), light, compact, and good beater lenses.

I'm actually adding a weather sealed kit (yeah, weather sealed kit) when I get the K7, I don't need it, probably won't use it much, but I like the idea of having a $200 lens I can beat the crap out of in any weather.

Hahah yeah always need a good beater, its part of the reason I don't want to upgrade to a 5D because the thought of dropping a $3000nz camera over a $800nz one lets me rest a little easier at night I dont think Ill sell my kit lens either, only get like $60.. whats the point.

Anyway, I like taking photos in low light, something about pure black in my photos, thats why I am keen to get something faster than f3.5 while I still have access to the discount.

Cool, you will have to let me know how you like it! That is one lens I really wish they made in an EF format, rather the EF-S, but it is killer on a crop camera. I use a 40d as a 2nd body right now, and still have a 20d as a back up, but we mostly use FF and the 1.3 crop, and I think all our future bodies will be one of those as well, so doesn't make sense for us right now.
